IMPROVEMENT IN PRESSER-FEET FOR SEWING-MACHINES.

Speciiication forming part of Letters Patent No. 116,380, dated June 27,1871.

To all 'whom it may concern:

Be it known that I, J AMES WENsLEY, of Philadelphia,in the county ofPhiladelphia and State of Pennsylvania, have invented a new and ImprovedPresser-Foot Attachment to Sewing-Machines; and I do hereby declare thatthe following is a full, clear, and exact description thereof, whichwill enable others skilled in the art to make and use the saine,reference being had to the accompanying drawing forming part of thisspecification.

Figure l is a side view, partly in section, of a presser-foot providedwith my improved attachment. Fig.2 is a transverse section of the same.Fig. 3 is a bottom view of the same. Fig. 4 is a top View of the same.

Similar letters of reference indicate correspon ding parts.

The object of my invention is to provide the presser-foot of asewing-machine with a stitchguide, whereby, especially in leather,sewing or stitching can be done exactly parallel with seams. Theinvent-ion consists in the improvement upon a presser-f0ot forleatherstitching, as hereinafter fully described and subsequentlypointed out in the claim.

A in the drawing represents a sewing-machine presser-foot of suitablekind and size. From its under side projects a feather or rib, a., whichis sufficiently thin to enter a seam and thereby guide the fabric to letthe stitching be parallel to the seam. The feather is secured to aspring, b, which is fastened to the shank of the presserfoot by a screwor rivet, c, the feather projecting through an orifice in thepresser-foot. The upper end of the spring is enlarged, as at el, andreceives a set-screw, c, whereby the spring can be set to regulate thedepth of the feather. f is a point or pin projecting from the end of thepresserfoot to serve as an eye-guide for the operator, .it being in linewith the feather and above the seam. Having thus described my invention,I claim as new and desire to secure by Letters Patent- The arrangement,upon a presser-foot, A, of the spring-pressed feather a, passingtherethrough, and the eye-guide f project-in g in front of and in linewith said feather, as and for the purpose specified.

The above specification of iny invention signed by me this 19th day ofApril, 1871.
